The first person to see DNA's potential beyond biology was Naiman Seeman, a chemist at New York University. More than twenty years ago, he began imagining how the genetic information in DNA might be engineered to perform useful tasks.

"DNA structures are programmable by sequence, and so are their intermolecular interactions," Seeman says. "That makes them unique."

Whereas nature alone dictates how most molecules interact, DNA comes with a built-in code that researchers can re-formulate to control which DNA molecules bond with each other. The goal of this DNA tinkering is microscopic factories that can produce made-to-order molecules, as well as electronic components 10 times smaller than current limits.

"Nanofabrication is where we are going," Seeman told LiveScience. "It will happen soon." More here
